Immense and detailed write-up of over four years of Exploring the Paris Metro system. Very beautiful photos, but I always find some discomfort with the reasoning given for risking your life and breaking the law; similar discomfort comes also from the term “urban explorer.” Yet I cannot deny the beauty of these photos.
